About the installation
About the installation
Hardly anything is as inviting as a crackling fireplace in the living room. Especially when the day at work has been long or you have been out for a walk in winter. A stove gives a room warmth and exudes a feeling of relaxation.
Unfortunately, many houses no longer have functional or accessible chimneys. Retrofitting is possible, but it is often associated with a lot of work and high costs. That's why a stainless steel chimney is ideal for this. A stainless steel chimney is versatile and flexible in use. So you can choose what you need according to your wishes. And if you don't know exactly what you need, we will be happy to advise you.
Depending on which variant of a stainless steel chimney you have, in some cases the chimneys have to be led around the eaves of the roof. For this you need our stainless steel elbows in the next step, each of which is bent at an angle of up to 30 °. Alternatively, you can also use a roof flashing. Please pay close attention to the assembly instructions. The wall brackets are then attached.
After the wall penetration is fixed, the tee element should be attached. The inspection length is attached to the lower end of the tee element, which in turn is placed on the anchor plate and screwed to a base support. The chimney can then be assembled from bottom to top step by step with our Twist-Lock System (saves up to 60% of the assembly time).
If you search for a used stainless steel chimney online, you will quickly find that you will find plenty of results. So if you are really interested in a used chimney, don't be fooled by photos and look at it once again in personal. But even so, there is still the risk that you will not be able to see all of the defects at first glance. Even if it is a stainless steel chimney, it is not always possible to immediately tell which fuels the previous owner used and whether the chimney was previously exposed to excessive moisture. In addition, you cannot see whether regular maintenance has been carried out, which is essential in order to properly comply with all fire protection regulations.
When you buy a chimney from us, you will receive professional advice and, if necessary, a cross-section calculation. After the purchase you will receive a manufacturer's guarantee and our declaration of performance from us. So you can be sure that your chimney also meets all the necessary fire protection regulations.
First, the wall penetration must be determined and planned. For this, an exact height must be determined, which determines at which point the wall is broken through. The opening must then be drawn on the wall. After that is done, the breakthrough can properly take place. Please note that the radius of the opening should be three centimetres larger than the radius of the wall penetration from the chimney to the flues. When you have mastered this, the connection piece can be fixed with help (e.g. with rock wool or cement).
Now the inner pipe must be mounted on the stove. You can insulate it with rock wool around the wall penetration in the wall opening. Outside, the wall can be filled with cement for example, so you can't see the rock wool anymore. Indoor you can also use gypsum. Now it's the right time to attach any wall finishing plates to blend everything on the wall, so it looks nice and neat.
Please refrain from a test run! First, your chimney sweeper should take a close look at the chimney and officially approve it. The test run can then be carried out together with a specialist.
Climate change is expected to be continually existing and consuming. That is why you should rethink your own consumer behavior in many situations and use used products as often as possible. With regard to stainless steel chimneys, however, you should be careful not to buy them used if possible. Since stainless steel chimneys have to meet strict requirements in order to be put into operation, you should rather get a new product. Because you know exactly what it is all about and where you are getting it from.
If, despite the risks, you have decided to buy a used stainless steel chimney and have previously received the approval of your chimney sweeper, you may at some point have to replace parts of your chimney. Please keep in mind that stainless steel fireplaces are often manufactured in batches. The appearance and the material often change in the batches. As a result, your chimney may no longer optically match, as e.g. the color of the spare part differs from the rest of the stainless steel chimney.
